ADJUSTABLE CIRCULAR HEEL FOR BOOTS ORSHOES.

SPECIFICATION forming part of Letters Patent No. 638,347, dated December 5, 1899.

Application filed June 5,1899. Serial No- '719,84=7. (No model.)

To all whom it may concern:

Be it known that I, THOMAS TINNOOK MAR- SHALL, a citizen of Canada, residing at Hamilton, in the county of Wentworth and Province of Ontario, Canada, have invented new and useful Improvements in Adjustable Circular Heels for Boots or Shoes, of which the following is a specification.

This invention relates to adjustable circular heels for boots and shoes, in which a circular metallic ring or plate is adj ustably attached and secured to the specially-prepared heel of a boot or shoe by means of a screw passing through the recessed center of the diametrical and raised arm of said ring and into a flanged nut, which is secured between the layers or lifts of said heel.

The objects of my invention are, first, to provide a boot or shoe the heelpart of which shall be very durable and com fortable to walk with; second, to provide a heel which when worn uneven-that is, more on one side than the other-the worn-down part shall be-capable of adjustment to any desired position in order that the unworn part may be in a position to be worn down and comparatively leveled, and, third, to afford facilities for the proper and perfect adjustment of the lower movable part of the heel. I attain these ob jects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a side elevation of a small-size boot having, this adjustable circular heel. Fig. 2 is an enlarged section of the heel part of the same. Fig. 3 shows the detached flanged nut. Fig. 4is a plan of the detached metallic ring, and Fig. 5 is the reverse or lower corrugated side of the same.

Similar letters and numerals refer to similar parts throughout the several views.

In the drawings the metallic ring or plate, which is corrugated on its lower wearing side, is indicated by A, its diametrical and raised arm by 2, and its dovetail circular recess by 3. This metallic ring A is secured-to the nut B by means of the screw 0, the head of which fits into a recess or countersink tin the lower and central part of the arm of the ring, the screw passing through the central hole 5 of the upper boss 6 of said arm and thence into the ring is worn off on one side.

perceptible from the exterior, and by reason of the arm being inserted the ring and the layer H will both be revolved or adjusted together and at the broken line X X, which adjustment may take place when one side of the This adj ustment is accomplished by means of a screwdriver acting in the nick of the screw-head. The lowest layer of leather, rubber, or other suitable material J, the edge of which is beveled to conform to the bevel or dovetailed cavity 3 of the ring, is forced therein and remains fixed. The central hole 7 of this layer J is for insertion of a screw-driver.

When the flanged nut B is inserted in position in and between the layers D and E of the heel, the said layers are secured together by means of nails, cement, or otherwise fastened and form a part of the heel part of a boot. It will be perceptible that the three lower parts that is, from the broken line X Xmove together when adjusted, the lower dovetailed layer being slightly rounding or convex, as shown, and assists very materially in the wear of the heel and prevents any annoying or unnatural sound. It will be noticed that space is allowed between the metallic nut and the boss on the upper side of the arm of the ring in order to allow the layer H to be firmly secured to the layer E. This is important as it prevents the layer E, hence the adjustable part of the heel, from turning unnecessarily.

This adjustable circular heel will be found to be a most durable, neat, and satisfactory device as applied to boots and shoes and easily adjusted to wearing position, as set forth, and specially adapted to all kinds of footwear and may be of very light or of heavy construction, as the case may be.

Various changes in the form, sizes, and proboss, and said raised arm terminating a disportions may be resorted to Without departtance from the outer sides of said ring, and ing from the spirit and scope thereof. Hence inserted into a layer of leather t0 revolve What I claim as my invention, and desire therewith, and to fasten by means of a screw I 5 5 to secure by Letters Patent, ispassing through a countersunk hole in said An adjustable circular heel for boots and arm-boss, and entering a rigid flanged nut shoes, consisting of a ring, its inner circle above said arm, as described.
